DISPENSING DEVICE.

Application filed June 25, 1926, Serial No, 118,437, and in France July 11, 1925.

The present invention relates to a recipientfor products of a semi-consistent nature, and chiefly for mustard, said recipient comprising means for the proper feeding of such products by a very simple opera tion, it being entirely closed when function ing so that the contents will be protected from dust and from contact withall external elements whereby it might become soiled or decomposed.

The appended drawing shows by way of example a sectional view of an embodiment of the invention.

In the example herein represented, the teeding vessel comprises a main body a at one end of which is formed the inclined conduit 5 leading to the exterior, its front part being cut at an angle. The main body is closed at the top by a screw cover 0 which is traversed at the centre by the cylindrical part (5 of a threaded rod 6 whichextends vertically through the whole recipient. At the lower end of said rod is the pivot portion f coacting with the recess 9 in the bottom of the vessel; on the top of the rod is mounted the milled knob h. The said rod is held in position by the stop or flange 'i, in contact with the said cover 'Upon the rod 6 is screwed a piston j which is vertically guided by a rib 7c engaging in a slot Z in the said piston. An annualar groove m may be formed in the said piston for an improved fiuidtight connection. Said tightness may be further improved by providing a cork washer a glued or otherwise secured to the bottom of the piston or it might be inserted in the groove on.

Theoperation is as follows:

To fill the said vessel, I unscrew the cover (1, and then take out the rod e and the piston j by means of the knob h. The product is poured in, and the said rod and piston are put in place and the cover 0 screwed on so as to maintain the whole. By proper tainer, a

1y turning the knob, the piston j is made to descend, thus compressing the product which is forced out through the conduit Z). After supplying the proper amount, the knob is turned slightly in the other direction in order to produce a slight suction, so that the product will not flow out when the device is inoperative.

Obviously, the said invention is not limited to the aforesaid forms of construction, which are given solely by way of example; in particular, the cover may be secured by other means, such for instance as a bayonet: device engaging suitable recesses.

Having now described my invention, what I claim new and desire to secure by Letters Patent is:

1. A dispensing device for semi-liquid substances comprising in combination a container, having a laterally disposed orifice at its lower end and a central recess in its bottom, a cover having a central opening screwed upon the upper end of said conscrew-threaded rod supported in said rec ss, a piston screwed on said rod, means on the piston ensuring a tight fit of the same in the container, an operating knob secured on said rod and having a diameter substantially-equal to or less than the central opening in the cover and projecting,

outwardly, a flange on the rod having a face upon which the cover is adapted to bear and a longitudinal rib on the inner surface of the container, adapted to engage into a longitudinal slot in the piston.

2. A dispensing device according to claim 1, in which the bottom of the container has a rounded inner face and the orifice is formed by a short conduit inclined upwardly and merging into the curvature of said inner face.

Intestimony whereof I have signed my name to this specification.
